用C＃解决此问题的最佳线程方法是什么？

Question

I have about 30 calculations that need to be done on a few thousand data points. The calculations are done in a 3rd party library. Each call can be done in parallel so I was thinking of putting the call into several threads.

The issue that I get is how to properly terminate the calls if need be. Since I don't have access to the lib which is where most of the time is, I can't exit the thread in a nice manner.

Any suggestions?

Thanks.

Answer 1

If the 3rd party library is a managed library, or spends most CPU time in managed code, you can call it from a separate appdomain and nuke the whole appdomain when you need to terminate calculations. If the calculations are mainly in unmanaged code, run the calculations as a separate process and nuke the whole process. Any other approaches are subtly dangerous and therefore unadvisable.
